摘要:通过包封配体和溶剂的氘化研究了 Ch 高振动模式对 Eu3+ 离子发光激发态的淬灭.新型多齿半球提供九个供体原子,与稀土离子形成整体中性配合物,分九步合成,允许轻松掺入氘原子 (11A-D.eu3+).在配体的芳环上引入叔丁基进一步提高了配合物在有机溶剂(29.eu3+和34.eu3+)中的溶解度.光物理研究,即发光光谱和寿命测量,表明 Eu3+ 激发态的显着猝灭是由附近的 Ch 振动模式引起的.将这些猝灭 Ch 模式替换为 Azacrown 桥中的 Cd 键导致发光寿命提高 1.5 倍.与氮杂冠桥氢原子(由 Md 计算确定)相比,与 Eu3+ 离子距离更大的悬垂臂的 Ch 高振动模式是效率较低的猝灭剂.由"horrocks 方程"估计的与 11A.eu3+,29.eu3+ 和 34.eu3+ 配位的甲醇分子数分别为 0.9,1.2 和 1.9,如 Md 计算所预测的那样.此外,实验数据表明,配体的

摘要:Polyfluoroalkylthio alcohols and esters thereof are disclosed with utility as intermediates for the synthesis of fluorochemicals with low free surface energies having oil and water repellent properties. The novel alcohols and esters are obtained by a free radical catalyzed addition of polyfluoroalkylthiols to acetylenic alcohols or esters thereof. The alcohols are employed in preparation of fluorine containing polyurethanes which are useful as finishes to provide oil and water repellency to textiles and as additives to plastics to provide mold release and other desirable properties.
